The Patient Protection and Affordable Care Act requires all individual and small-group plans to offer a package of 10 "essential health benefits" starting in 2014. The EHB package includes requirements for dental and vision services for children.

Dental policymakers have come up with the following terms to refer to exchange plans:

PPACA lets exchanges offer "0.5 plans," or stand-alone dental plans, but it's not clear whether consumers can use the new PPACA health insurance tax credits to pay for stand-alone dental. Exchanges have not been sure to apply PPACA plan design rules to stand-alone dental.

This year, a carrier can make any QHP a 9.5 plan if the issuer is selling the QHP through an exchange that offers stand-alone dental.

Some children's advocates are afraid the allowing the sale of 9.5 plans will lead some parents to go without dental coverage for their children.

The Covered California board is thinking of requiring QHPs to embed pediatric dental benefits and getting rid of 0.5 plans, or possibly allowing the sale of both 10.0 and 9.5 plans along with 0.5 plans. The consultants estimated an all-10.0-plan approach could cut the cost of pediatric dental to $3 per child per month, from $15 per month for options involving 0.5 plans.

Speakers from carrier groups emphasized that their main interest is in seeing Covered California make decisions about 2015 plans quickly.

Allison Barnett of Anthem Blue Cross, a unit of WellPoint, said her company thinks all QHPs should be 10.0 plans.

Dental carriers and dental groups pushed for the exchange to continue to allow the sale of 0.5 plans, and to get the Internal Revenue Service to resolve any tax questions.

The Kentucky and Nevada exchanges have had good success this year with offering 0.5 plans alongside 9.5 plans and 10.0 plans, and "we haven't seen any complexity issues," said Pam Loomis, who spoke for the California Association of Dental Plans.

Jim Mullen of Delta Dental noted that, in the commercial market, consumers now get 98 percent of their dental coverage from stand-alone plans.
